Calibrated files will always be '.txt'
Calibrated files will always be '.txt'

HappyTools would retain the extension of the original data when performing calibration during batchprocess. The result was that if a user started with '.awr' or '.csv' files that the quantitation wouldn't occur as that expects a '.txt' file.

This build addresses that by using `Path(location).stem + '.'txt'` instead of `Path(location).name`.
